Question

BlackTom AI · Accepted Answer

About 7% of the world’s oceans are currently designated as protected areas.

1) Relevant knowledge points and concepts:
- A marine protected area (MPA) is a region of the ocean where human activity is managed to conserve biodiversity and ecosystem services.  
- International conservation targets (e.g., the Aichi Target 11 aimed for 10% by 2020, and more recent calls aim for 30% by 2030), so comparison to current coverage is often used to show shortfalls.

2) Step‑by‑step reasoning:
- The lecture gives the specific statistic for global ocean protection coverage. That figure is reported as 7%.  
- This percentage is a straightforward factual figure from the lecture, not derived from other premises in the question.

3) Calculation (intermediate steps to interpret the percent as area):
- World ocean area ≈ 361 million km².  
- 7% of 361 million km² = 0.07 × 361,000,000 km² = 25,270,000 km².  
- So about 25.3 million km² of ocean are under some form of protection, corresponding to the 7% figure.

4) Why the correct answer is correct:
- The lecture explicitly states that roughly 7% of oceans are protected globally; therefore the factual completion of the sentence is the number 7. The calculation above simply converts that percentage into an approximate area to give context; it does not change the given percentage.

5) Why other numbers would be incorrect:
- Values like 3%, 10% or 30% are commonly discussed in policy contexts (3% could be an older baseline, 10% was an Aichi target, 30% is a proposed future goal), but none of these match the lecture’s stated current coverage. The authoritative lecture figure is 7%, so those alternatives are incorrect for this question.

6) Conclusion:
- Confirmed final answer: 7 (i.e., about 7% of oceans are protected globally).
